Getting started
- What products and services do you offer for drug discovery research?
- What methods of detection do you offer for the various druggable target classes?
- What is the first consideration for getting started with a ratiometric fluorescent assay?
- I think that many of my test compounds may not be active, what is the best approach to screening?
- What sort of dilution series is recommended to determine an EC50 or an IC50?
Troubleshooting
- I have no assay window in my drug discovery assay. Why is this?
- I have no assay window in my TR-FRET Assay. What is the reason?
- My EC50 (or IC50) results are different from a colleague’s in another lab. Why?
- Is a 30-fold window better than a 10-fold window in a drug discovery assay?
